Hochfrequent

Hochfrequent is a German adjective used to describe phenomena, devices, or signals that operate at high frequencies. In technical contexts it is a translation of the English term high-frequency and is common in fields such as electrical engineering, radio communications, optics, and medicine. The corresponding noun is Hochfrequenz.

In everyday technical German you will encounter phrases such as hochfrequentes Signal, hochfrequente Wellen, or in compound terms like Hochfrequenztechnik (RF engineering) and Hochfrequenzbereich (high-frequency range). The exact frequency span associated with “hoch” varies by discipline but generally denotes frequencies from the kilohertz up to the gigahertz and beyond, depending on context.

Grammar and usage notes: as an adjective, hochfrequent is declined according to standard German rules, e.g., das hochfrequente Signal, die hochfrequenten Signale, der hochfrequente Frequenzbereich. The term is more common in technical writing than in everyday speech and is closely related to other German terms for frequency domains such as Niederfrequenz (low frequency) and Hochfrequenz (high frequency).
